Icma 451 | SEMPIGAS® female straight press-fitting

SEMPIGAS press fittings for multi-layer pipes are designed for use in domestic gas supply systems.
SEMPIGAS press fittings differ from traditional products of this kind because they are implemented
applying precautions that safeguard the health of users. This is done through a careful selection of
the materials and processing operations aimed at keeping potentially dangerous substances from
being released in potable water.
SEMPIGAS press fittings are easy to install. The materials used to make SEMPIGAS fittings comply
with the strictest standards of safety applied to materials that come into contact with water used
for human consumption. Used in combination with multi-layer pipes, SEMPIGAS fittings constitute a
SAFE, FAST and COST-EFFECTIVE press system.
SEMPIGAS system is certified UNI 11344:2014.

SEMPIGAS press fittings are designed for installation making use of the radial pressing method.
This type of joint has become increasingly popular as a result of the simplicity and speed with which
it is installed. The fitting is also perfectly water-tight, even when subjected to high pressures and
temperatures.
The clamp, made specifically to fit any diameter size of the multi-layer pipes utilized, presses against
the stainless-steel bearing that secures the pipe to the fitting.
The mechanical seal is ensured by the particular body gauge of the fitting and by the relative steel
bearing, which have been designed for pressing with three different clamp gauges; these gauges
are: TH.
The wet seal is ensured by two O-rings.
After pressing, SEMPIGAS fittings form a connection between the pipe and fitting so as to provide
maximum stability and wear.
